8.1Cannot Detect the Modem

1.Verify that your modem is connected to your Ethernet LAN.

Please check and see if the power adapter and cord are connected properly to the NetDSL. Make sure you switch the power switch to ON.

If you are connecting your NetDSL to an Ethernet network hub, use a straight-through Ethernet cable, and make sure you are connecting to the uplink port of the hub. If an uplink port is unavailable, use a cross- over Ethernet cable and connect it to a non-uplink port.

If you are connecting your NetDSL to an Ethernet network PC, then use a straight-through Ethernet cable.

Note: See Appendix B “Ethernet Cable Pinout” for further information about the differences between a straight-through and a crossover Ethernet cable.

Another way you can confirm that there is a physical connection to your LAN is by checking the LED located on the front panel of the NetDSL modem. The LAN Link LED of will lit green to indicate a valid LAN connection. If the LAN Link LED of is not green, then check the connection between the modem and your LAN. Re-start the NetDSL Manager to see if it can detect the modem.

3.Please select “Specify an IP Address” in TCP/IP Properties for Windows 95/ 98 or Windows NT 4.0. Set your IP Address to a value between 192.168.1.2 and 192.168.1.254, the Subnet Mask to 255.255.255.0, and the Gateway as 192.168.1.1. When prompted, restart your computer otherwise do so manually. Re-start NetDSL Manager to see if it can detect the modem.
